Important Safety Instructions
All electrical work must be performed by a licensed electrician and conform to all national, state,
and local codes. When installing and using this electrical equipment, basic safety precautions
should always be followed, including the following:
DANGER: To reduce the risk of injury, do not remove the suction fittings of your spa or hot tub.
Never operate a spa or hot tub if the suction fittings are broken or missing. Never replace a
suction fitting with one rated less than the flow rate marked on the equipment assembly.
WARNING: Prolonged immersion in hot water may induce hyperthermia. Hyperthermia occurs
when the internal temperature of the body reaches a level several degrees above the normal
body temperature of 98.6°F. The symptoms of hyperthermia include dizziness, fainting,
drowsiness, lethargy, and an increase in the internal temperature of the body. The effects of
hyperthermia include: 1) unawareness of impending danger; 2) failure to perceive heat; 3)
failure to recognize the need to exit spa; 4) physical inability to exit spa; 5) fetal damage in
pregnant women; 6) unconsciousness resulting in a danger of drowning.
WARNING: To Reduce the Risk of Injury —
The water in a spa should never exceed 104°F (40°C). Water temperatures between 100°F •
(38°C) and 104°F (40°C) are considered safe for a healthy adult. Lower water temperatures are
recommended for young children and when spa use exceeds 10 minutes.
Since excessive water temperatures have a high potential for causing fetal damage during •
the early months of pregnancy, pregnant or possibly pregnant women should limit spa water
temperatures to 100°F (38°C).
Before entering a spa or hot tub, the user should measure the water temperature with an •
accurate thermometer since the tolerance of water temperature-regulating devices varies.
The use of alcohol, drugs, or medication before or during spa or hot tub use may lead to •
unconsciousness with the possibility of drowning.
Obese people and people with history of heart disease, low or high blood pressure, •
circulatory system problems, or diabetes should consult a physician before using a spa.
People using medication should consult a physician before using a spa or hot tub since some •
medication may induce drowsiness while other medication may affect heart rate, blood
pressure, and circulation.
WARNING: Risk of electric shock – Install the control center at least five (5) feet (152.4cm)
from the inside wall of the pool and/or hot tub using non-metallic plumbing. Canadian
installations must be at least three (3) meters from the water.
